At $150, I can't say you still got a bad deal, unless it was hot or had been run over by a tank. I don't know how many rounds an M&P 9mm barrel is good for, but the late Todd Greene had tested one on his website and ran over 50k rounds thru it before it got retired to a cracked frame or something. I've got a 9FS with the supposedly "good" barrel accuracy wise, and am not all that impressed. Most of my shooting for tight groups has been in an indoor range, however,, and for some reason I don't shoot as good indoors. Outdoors, I have gotten probably 12-inch groups out to 50 yards. Hard to say if it's me, the ammo, or the gun, but the "me" is probably a contributing factor.

For 150 bucks, you've got a pistol that is a good start for a custom/enhancement project for competition. Like everyone else, I'd suggest a gunsmith-fitted barrel for the most gains in accuracy as long as everything else is more or less functioning properly.
